The maker's website gives 3.5 cfm:
http://ramsond.com/proddetail.php?prod=CUT50DY

It doesn't really specify whether that is 3.5 scfm (ie 3.5 cf after
expanding to 1 atmosphere) or acfm (actual 3.5 cf of compressed air), but
usually air tools are given as inlet acfm, meaning it needs roughly 17 scfm
(at 4 atmospheres/60 psi).
